DSA showed a complete occluded small aneurysm treated by LVIS stent-assisted coiling (A, B, C, arrows). In immediately postprocedural angiographic images, the aneurysm showed a residual neck (B, arrow). At 6-month follow-up, DSA indicated that the aneurysm had complete occlusion (C, arrow). In hemodynamic simulation, the velocity streamline was decreased (D, arrows), velocity in the aneurysm and wall shear stress was decreased (E and F, arrows), and the velocity of the aneurysm neck plane was also markedly reduced (G, arrows) after treatment
